Electronic Ballast Controller

The KA7541 provides simple and high performance electronic ballast control functions. KA7541 is optimized for electronic ballast requiring a minimum board area, reduced component count and low power dissipation. Internal soft start circuitry eliminates the need for an external soft start PTC resistor. The initial soft start switching frequency and soft start time CAN be adjusted depending on the types of lamps. Protection circuitry has also been added to prevent burning out of switches in no lamp condition. Output Gate drive circuit clamps Power MOSFET Gate voltage irrespective of supply voltage.
